This book invites the reader to understand our Universe, not just marvel at it. From the clock-like motions of the planets to the catastrophic collapse of a star into a black hole, gravity controls the Universe. Gravity is central to modern physics, helping to answer the deepest questions about the nature of time, the origin of the Universe and the unification of the forces of nature. Linking key experiments and observations through careful physical reasoning, the author builds the reader's insight step-by-step from simple but profound facts about gravity on Earth to the frontiers of research. Topics covered include the nature of stars and galaxies, the mysteries of dark matter and dark energy, black holes, gravitational waves, inflation and the Big Bang. Suitable for general readers and for undergraduate courses, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity.

Quantum computing — the application of quantum mechanics to information — represents a fundamental break from classical information and promises to dramatically increase a computer's power. Many difficult problems, such as the factorization of large numbers, have so far resisted attack by classical computers yet are easily solved with quantum computers. If they become feasible, quantum computers will end standard practices such as RSA encryption.Most of the books or papers on quantum computing require (or assume) prior knowledge of certain areas such as linear algebra or quantum mechanics. The majority of the currently-available literature is hard to understand for the average computer enthusiast or interested layman. This text attempts to teach quantum computing from the ground up in an easily readable way, providing a comprehensive tutorial that includes all the necessary mathematics, computer science and physics.

The location of an object can often be determined from indirect measurements using a process called estimation. This book explains the mathematical formulation of location-estimation problems and the statistical properties of these mathematical models. It also presents algorithms that are used to resolve these models to obtain location estimates, including the simplest linear models, nonlinear models (location estimation using satellite navigation systems and estimation of the signal arrival time from those satellites), dynamical systems (estimation of an entire path taken by a vehicle), and models with integer ambiguities (GPS location estimation that is centimeter-level accurate). Location Estimation from the Ground Up clearly presents analytic and algorithmic topics not covered in other books, including simple algorithms for Kalman filtering and smoothing, the solution of separable nonlinear optimization problems, estimation with integer ambiguities, and the implicit-function approach to estimating covariance matrices when the estimator is a minimizer or maximizer. It takes a unified approach to estimation while highlighting the differences between classes of estimation problems. The only book on estimation written for math and computer science students and graduates, it includes problems at the end of each chapter, many with solutions, to help readers deepen their understanding of the material and guide them through small programming projects that apply theory and algorithms to the solution of real-world location-estimation problems. The book’s core audience consists of engineers, including software engineers and algorithm developers, and graduate students who work on location-estimation projects and who need help translating the theory into algorithms, code, and deep understanding of the problem in front of them. Instructors in mathematics, computer science, and engineering may also find the book of interest as a primary or supplementary text for courses in location estimation and navigation.

Where do neighborhoods come from and why do certain resources and effects--such as social capital and collective efficacy--bundle together in some neighborhoods and not in others? From the Ground Up argues that neighborhood communities emerge from neighbor networks, and shows that these social relations are unique because of particular geographic qualities. Highlighting the linked importance of geography and children to the emergence of neighborhood communities, Rick Grannis models how neighboring progresses through four stages: when geography allows individuals to be conveniently available to one another; when they have passive contacts or unintentional encounters; when they actually initiate contact; and when they engage in activities indicating trust or shared norms and values. Seamlessly integrating discussions of geography, household characteristics, and lifestyle, Grannis demonstrates that neighborhood communities exhibit dynamic processes throughout the different stages. He examines the households that relocate in order to choose their neighbors, the choices of interactions that develop, and the exchange of beliefs and influence that impact neighborhood communities over time. Grannis also introduces and explores two geographic concepts--t-communities and street islands--to capture the subtle features constraining residents' perceptions of their environment and community. Basing findings on thousands of interviews conducted through door-to-door canvassing in the Los Angeles area as well as other neighborhood communities, From the Ground Up reveals the different ways neighborhoods function and why these differences matter.

As long as our minds are dominated by the conditions of the external world, we are bound to remain in a state of dissatisfaction, always vulnerable to grief and fear. How then can we develop an inner sense of well-being and redefine our relationship to a world that seems unavoidably painful and unkind? Many have found a practical answer to that question in the teachings of Tibetan Buddhism. Here at last is an organized overview of these teachings, beginning with the basic themes of the sutras--the general discourses of the Buddha--and continuing through the esoteric concepts and advanced practices of Tantra. Unlike other introductions to Tibetan Buddhism, this accessible, enjoyable work doesn't stop with theory and history, but relates timeless spiritual principles to the pressing issues of modern life, both in terms of our daily experience and our uniquely Western world view. This fascinating, highly readable book asks neither unquestioning faith nor blind obedience to abstract concepts or religious beliefs. Rather, it challenges us to question and investigate life's issues for ourselves in the light of an ancient and effective approach to the sufferings and joys of the human condition.

Eminent biophysicist Loewenstein seeks an answer in the mechanisms of physics. Bringing information theory--the idea that all information can be quantified and encoded in bits--to bear on recent advances in the neurosciences, he reveals a web of immense computational power inside the brain.

Designed for the intellectually curious, this book provides a solid foundation in basic probability theory in a charming style, without technical jargon. This text will immerse the reader in a mathematical view of the world, and teach them techniques to solve real-world problems both inside and outside the casino.
